Final answer:
The answer discusses the minimum weather conditions required for an airport to be an alternate in a dispatch release, focusing on visibility and cloud ceiling standards specified in the TAF or operator's AOC specifications.
Step-by-step explanation:
The minimum weather conditions that must exist for an airport to be listed as an alternate in the dispatch release for domestic flight operations generally relate to the visibility and cloud ceiling standards that must be met either at the time of arrival or within a certain time window around the expected time of arrival. These conditions are typically specified either by the Terminal Aerodrome Forecast (TAF) for the alternate airport and/or the operator's Approved Operating Certificate (AOC) specifications. While the TAF provides expected meteorological conditions for a set period, the AOC specifications might dictate certain additional requirements that are tailored to the operator's capabilities and the specific performance of their aircraft.
It's important to note that the question provided does not directly relate to the documentation mentioned regarding the transportation of animals and regulations set by the Department of Transportation (DOT). The primary concern here is weather minimums for flight operations and choosing an alternate airport, not animal transportation policies.
